Abstract:

Aiming at the problems of being vulnerable to internal attacks and frequent link interruption in flying ad hoc networks (FANETs), a trust-based ad hoc on-demand multipath distance vector routing protocol (TAOMDV) is proposed. Firstly, a trust evaluation model is established. The packet forward ratio, trusted interaction and probe packet receive ratio are introduced as trust evaluation factors. An adaptive fuzzy trust aggregation network (AFTAN) is designed to calculate the direct trust of nodes, while the indirect trust of reliable neighbor nodes is integrated as well to calculate node trust. Secondly, the trust fluctuation penalty mechanism is introduced to resist the on-off attack in the trust model. Finally, the trust model is applied to ad hoc on-demand multipath distance vector (AOMDV) protocol. In the route discovery phase, the path trust is introduced as the basis for routing selection to establish a trusted path. In the route maintenance phase, the path alarm mechanism is applied to respond to malicious nodes in a timely manner. The simulation results show that the TAOMDV can not only defend against common attacks, such as black hole attack, gray hole attack and on-off attack, but also reduce the impact of topology changes and link interruptions. Compared with light-weight trust-enhanced ad hoc on-demand multipath distance vector (TEAOMDV), the proposed protocol effectively improves the delivery ratio and throughput of the network, which contributes to the better performance in routing overhead and average end-to-end delay.

摘要:

针对无人机自组织网络(FANETs)容易遭受内部攻击、链路中断频繁的问题,提出了一种基于信任的按需多径距离矢量路由协议(TAOMDV)。首先,建立了节点信任度评估模型,引入数据包转发率、可信交互度、探测包接收率作为信任评估因子,设计了自适应模糊信任聚合网络(AFTAN)计算节点的直接信任度,综合可信邻居节点的间接信任度以计算节点信任度。其次,引入信任波动惩罚机制,抵御信任模型中的开关攻击。最后,将信任模型应用于按需多径距离矢量路由协议(AOMDV)中,在路由发现阶段引入路径信任度作为路由选择依据,建立可信路径,在路由维护阶段通过路径报警机制对恶意节点做出及时响应。仿真结果表明TAOMDV不仅能抵御常见的黑洞、灰洞攻击与开关攻击,而且能够降低网络拓扑变更与链路中断的影响。与轻量级信任增强路由协议(TEAOMDV)相比,有效提高了网络的数据包投递率与吞吐量,优化了路由开销与平均端到端时延。
